Each year, MMI students are challenged with preparing special research projects that are displayed at the annual Open House event. Open House is held on a Sunday in the spring.

All MMI students, from sixth-graders to seniors, display, explain, and demonstrate their projects in classrooms and locations throughout the school.

Visitors are able to observe a variety of student projects, including many in the areas of literature, mathematics, science, and social studies. In addition, food projects, prepared primarily by world language students, are featured.

The food, which is available for sampling, is served in an atmosphere authentic to the nation of the food’s origin. Non-food projects are open to the public from 2:00 P.M.-4:00 P.M., and culinary projects are open to the public from 2:30 P.M.-4:30 P.M.

All projects have been prepared by MMI students under the guidance of faculty advisers. Each project is then evaluated during Open House by a panel of judges from the Hazleton Campus of Penn State. MMI's in-house Chef evaluates the food projects. The winners are then honored at a special assembly.
